Show original supplier description
The RC Engineering SL4-0440 Saturated Injector is engineered for modified vehicles, offering a high-performance solution for street/strip and race applications. With a flow rate of 440cc/min (42 LBS/HR) at 30-100 PSIG, they are suitable for naturally aspirated, turbocharged, or nitrous-fed setups. Saturated injectors are required for vehicles that do not use an injector resistor box, such as later model Hondas. It is recommended to verify your vehicle's requirements or consult a mechanic before ordering. The injectors operate on 8-15V with a 1.0 Amp rating and 12.5 Ohms resistance. Injectors are sold individually. For a 4-cylinder vehicle, an order quantity of four injectors is necessary.
